The Milky Way’s New Spiral Arm

Early textbook drawings of our galaxy may show many spiral arms around a spherical nucleus. Then a bar was found in the galaxy’s center . .. then the number of arms went to four . . .then to two. It’s tough to see on the other side of the nucleus, though. But, as was reported at the recent American Astronomical Society meeting, using only a 4-foot dish on the roof of the Center for Astrophysics in Cambridge, the 60,000 light year long tip of a spiral arm was found using Carbon Monoxide emission. As illustrated in the diagram (courtesy of Sky & Telescope), you can now see what the galaxy may look like . . .or the latest rendition anyway!
